Be interested in seeing your wiring diagram. Am all open to simplifying any extra wiring. One advantage and reason I used the relays is to have a higher current capacity so all the motor current is not going thru the switch. Another is to enable a built in braking function typical of permanent magnet motors when the leads to still spinning armature coils are connected together as power is removed.

That braking feature is probably not that applicable in normal window use since the switch is not as likely to be released in mid travel as it is after the window hits a stop. If that braking feature goes away it probably won't be noticed.
